[0001] 本申请基于2011年10月7日向日本专利局提出的日本专利申请N0.2011-222404和N0.2011-222536,其所有内容被援引至此。 [0001] This application is based on Japanese patent filed in the Japan Patent Office on October 7, 2011 to apply N0.2011-222404 and N0.2011-222536, all of its contents are hereby incorporated by reference.

技术领域 FIELD

[0002] 本发明涉及图像形成装置,尤其涉及复印机、传真机、各种打印机等图像形成装置。 [0002] The present invention relates to an image forming apparatus, particularly to an image copying machine, a facsimile machine, a printer, various forming apparatus.

背景技术 Background technique

[0003] 电子照片式的图像形成装置中存在具有扫描功能、传真功能、复印功能、作为打印机的功能、数据通信功能以及服务器功能的MFP (Multi Funct1n Peripheral)、传真机装置、复印机、打印机等。 [0003] The electrophotographic type image forming apparatus having a scanning function is present, a facsimile function, a copy function, a printer function, a data communication function and a server function MFP (Multi Funct1n Peripheral), a facsimile apparatus, a copying machine, printer or the like.

[0004] 由于对世界的环境的关心的高涨、省能量志向的高涨、或者二氧化碳的排出量削减志向的高涨,对削减以MFP为代表的图像形成装置的消耗电量的期望正在提高。 [0004] Due to rising concerns on the world's environment, the provincial energy aspirations high, or rising carbon dioxide emission reduction ambitions, to reduce the image forming MFP as the representative of the power consumption of the device is expected to improve. 为了以能够对省电力作出贡献的方法(不违反省电力的方法)使用图像形成装置,以不违反省电力的方法使用图像形成装置,或者为使用户确认能够可靠地实施电力的削减,提出了显示图像形成装置的消耗电量的功能、经由网络向图像形成装置外的计算机等提供图像形成装置的消耗电量的功能等。 In order to process (method does not violate power saving) can contribute to power saving using an image forming apparatus, to a method does not violate the power saving of the image forming apparatus, or to enable a user to confirm reduction can reliably embodiment power is proposed display image forming function of the power consumption of the device, computer or the like to provide the function of the apparatus outside the image forming apparatus consumes power to the image forming via a network. 但是,对于精度良好地测量或者计算图像形成装置的消耗电量的技术,还未充分被提出。 However, accurately measured or calculated consumption amount of the image forming apparatus of the technology has not yet fully been proposed.

[0005] 本来,图像形成装置的消耗电量根据图像形成装置的动作状态而变化。 [0005] Originally, the power consumption of the device varies depending on the operation state of the image forming apparatus forming an image. 例如,无等待时间、可以打印的状态即待机状态比使一部分的功能停止的状态即省电力状态的消耗电力多。 For example, no waiting time, i.e., the state of print standby state than a part of the function that is in a stopped state save more power consumption power state. 另外,图像形成装置进行彩色打印的状态比图像形成装置进行单色打印的状态的消耗电力多。 Further state consumption state, the image forming apparatus prints a color image forming apparatus than the electric power multiple monochromatic printing. 对于现有的显示消耗电量的功能而言,在用户变更了移向省电力状态前的时间所涉及的设定等节能功能所涉及的设定的情况下、图像形成装置开始了推荐单色打印的模式的情况下等,重视用户能够切身感受到规定期间后的消耗电量与以前的消耗电量相比有所降低。 For the case where the power consumption of the conventional display function, the user changes the setting in the setting time before saving features such as power saving state directed toward the concerned image forming apparatus starts a printing monochrome Recommended such as the case of the mode, the user can feel the importance of a specified period after the power consumption compared to the previous power consumption decreased. 因此,并不重视显示的消耗电量的精度的高低,未采取对消耗电量的精度进行提高的对策。 Therefore, we do not pay attention to the level of accuracy of the power consumption of the display, not to take measures to improve the accuracy of the power consumption of conduct.

[0006] 但是,由于对地球温暖化的危机感的高涨,并且用具体的数值目标推进二氧化碳的排出削减量的世界的运动,其状况也在变化。 [0006] However, due to global warming rising sense of crisis, and promote the movement of world carbon dioxide emissions reductions with specific numerical targets, their situation is changing. 例如在公司、事务所中,通常通过对其管理对象范围内的空调、图像形成装置等各种设备,按各设备求出“消耗电力削减量”、“根据消耗电力削减量计算出的二氧化碳的排出削减量”,来计算管理对象范围整体的排出削减量。 For example, in companies and offices usually conditioned by its management target range, the image forming apparatus of various devices, each device is determined by the "power consumption reduction amount", the "power reduction amount is calculated from the consumption of carbon dioxide discharge reductions "to calculate the overall management of the target range of discharge reduction. 进而,对于未达成排出削减量的目标的设备,通常执行进一步的改善对策。 Furthermore, the device for discharge reductions did not reach the goal, usually perform further improvement measures. 结果,要谋求图像形成装置提供的消耗电力信息的高精度。 As a result, the power consumption information to seek to provide an image forming apparatus with high accuracy.

[0007]另外,各种设备的消耗电量、各设备占总消耗电量的消耗电量的比率随季节变化。 [0007] Further, power consumption of various devices, the ratio of the total power consumption of each device's power consumption changes with the seasons. 例如,空调的消耗电力随季节而变化,但电梯等消耗电力整年间几乎是恒定的。 For example, air-conditioning power consumption varies with the seasons, but the elevators consume whole years of almost constant power. 因此,分配给图像形成装置等各个装置的消耗电力削减量、目标的消耗电量按月不同,需要与上一年的同月相比较。 Therefore, the power consumption of each device to the image forming devices assigned to cut the amount of electricity consumed monthly target different needs compared to the same month of the previous year. 即,正从谋求能够理解图像形成装置的消耗电量的定性的变化的时代向谋求能够理解图像形成装置的消耗电量的定量的变化的时代变化。 I.e., positive images can be appreciated that a qualitative change from the power consumption amount sought forming apparatus to seek times can be appreciated that quantitative changes in the changing times the power consumption of the image forming apparatus.

[0008] 现有的谋求图像形成装置的消耗电量的现有的方法例如在下述文献1以及2中公开。 The conventional method of [0008] a conventional amount to seek the image forming apparatus is consumed, for example, disclosed in the following Documents 1 and 2.

[0009] 下述文献1中公开了基于印刷设定、印刷张数以及印刷份数的计数结果,来计算节能度的技术。 [0009] The following Document 1 discloses a technique based on the count result of print setting, number of printed sheets and the number of copies of a power saving degrees. 下述文献1的技术中,将消耗电量的计算设定为“消耗电力=(复印时的消耗电力A) X (印刷运转时间X) + (休眠时的消耗电力BX (休眠中时间Y) + (FAX时的消耗电力C) X (FAX运转时间Z)”。假设上述固定值A、B及C可以是任意的固定值。 Technical Document 1 below, the calculated power consumption amount is set to "= power consumption (power consumption when the copy A) X-(print operation time X) + (power consumption when BX sleep (sleep time Y) + (C power consumption when the FAX) X (FAX the Z operation time). "Suppose the fixed values ​​a, B, and C may be any fixed value.

[0010] 下述文献2中公开了下述技术,即通过AC/DC变换器将来自外部电力源的交流电力变换为24V的直流电力,利用与AC/DC变换器直接连接的累计电量计来测量复合机的消耗电量。 [0010] Document 2 described below discloses a technique, i.e. by converting AC power AC / DC converter from an external power source for 24V DC power, the accumulated power with the use of AC / DC converter is directly connected to the meter measuring the consumption amount of the multifunction peripheral.

[0011] 另外,提出了下述图像形成装置,即以求出图像形成装置消耗的电量,支援使用者、管理者的省电力化的对策为目的,具有显示或者总计电力使用状况的功能。 [0011] Further, the following is proposed an image forming apparatus, i.e., in order to consume the power of the image forming apparatus, the user support, the power of the countermeasure for the purpose of saving manager, a display or a total power usage of functions.

[0012] 以往,通过测量初级侧(图像形成装置的变压器前的商用电源侦D的电源电压和负载电流,来测量图像形成装置的消耗电量。例如下述文献3中,公开了下述技术,即计测作为省电力模式的时间,根据计测出的时间和预先测量的通常电力模式下的单位消耗电力,计算通常电力模式时的假想的消耗电力,将通常电力模式时的假想的消耗电量与省电力模式的消耗电量的差计算为省电力模式的电力削减值。 [0012] Conventionally, by measuring the primary side (the image formation before the supply voltage and load current of the commercial power transformer investigation apparatus D, the apparatus for measuring power consumption amount of the image formed, for example, following Document 3 discloses a technique, i.e., measured as the time power mode saving consumption according to the unit under measurement the time and measured in advance of the normal power mode power, the virtual power consumption when calculating the normal power mode, the virtual power consumption during the normal power mode calculate the difference between the power consumption of the power-saving mode to save power mode power reduction value.

[0013] 另外,下述文献4中公开了下述技术,即通过测量从商用电源供给给图像形成装置主体的电流值以及电压值来计算消耗电量。 [0013] Further, Document 4 below discloses a technique in which a current value and a voltage value of the device body by measuring the power consumption is calculated from the commercial power supply to the image. 在该技术中,当用户发出了印刷指示时,生成在用户发出的印刷指示的图像数据上增加了电力信息通知的图像数据的图像数据,并将该图像数据印刷于规定的纸张。 In this technique, when the user issues a printing instruction, image data to generate image data increases power information notified on the image data of the print instruction issued by the user, and print the image data on a predetermined sheet.

[0018] 但是,文献1的技术存在通过计算求出的消耗电量的精度低这一问题。 [0018] However, in Document 1 there is a low power consumption amount by calculation accuracy problem.

[0019]例如,复印时的消耗电力根据复印模式而较大地变化。 [0019] For example, when the power consumption of the copying changes greatly depending on the copy mode. 因为复印模式存在多个。 Because there are multiple copy mode. 例如,若供给复印中使用的纸张的供纸口不同,则使用的电机的数量、种类不同。 For example, if different feeding copying paper used in the paper supply port, the number of motors is used, different types. 另外,彩色模式的情况下,4色的感光体分别旋转,另一方面,单色模式的情况下,仅1色的感光体旋转,因而使感光体旋转的电机的消耗电力在彩色模式与复印模式中较大地变化。 Further, in the case of the color mode, color photoreceptor 4 are rotated, on the other hand, in the case of the monochromatic mode, only one color of photosensitive body is rotated, thus the power consumption of the motor rotating the photosensitive member in the color mode to the copy pattern changes greatly. 另外,若纸张尺寸不同,则各部件的动作时间也不同。 Further, when different paper sizes, the operation time of each member is different. 另外,消耗电力也较大地依赖于来自作为电子照片处理的主要的构成之一的高压电源的电压或者电流的值。 Further, the power consumption is also largely dependent on the value of the voltage or current from the high voltage supply as one of the major constituent of the electrophotographic process. 电压或者电流通过所谓的图像稳定化控制,根据使用环境来决定适当的值。 Voltage or current by a so-called image stabilization control, depending on the environment to determine the appropriate value. 另外,消耗电力根据温度、湿度等环境的变动而变化。 Further, the power consumption varies according to changes in temperature and humidity environment. 在低温环境化下,由于润滑脂的硬化,齿轮、轴承这样的部件的负载转矩增加。 In the environment of low temperature, due to the hardening of the load torque, gear, bearing grease such components is increased. 因此也存在下述情况,即作为用于求出消耗电量的参数,不得不根据环境准备不同的值。 Thus there is a case where the power consumption amount as a parameter for determining, according to the environment have to prepare different values.

[0020] 因此,消耗电量的计算所需的上述固定值A、B以及C等参数为多个,为了提高消耗电量的精度,需要用于确定数量较多的参数的庞大的作业以及设计工时,因而不实用。 [0020] Thus, the power consumption amount required for the calculation of the fixed values ​​A, B and C of a plurality of parameters, in order to improve the accuracy of power consumption amount, it is necessary to determine a larger number of design man-hours and large job parameters, which is not practical.

[0021] 进而,深刻的问题是伴随图像形成装置的历时变化的消耗电力的变动的处理。 [0021] Furthermore, the problem is a process accompanied by profound changes over the image forming apparatus changes the power consumption is. 对于轴承、感光体或者转印带等清洁部件产生因摩擦引起的负载转矩而言,由于历时变化或者耐久变化,该负载转矩变化。 A bearing member for cleaning the photoreceptor or a transfer belt load torque generated by the friction, since changes over time or endurance change of the load torque variation. 因此,即使在相同的动作模式下打印,半年前、1年前与现在的负载的状态不同。 Therefore, even if the print in the same operation mode, six months ago, a year ago with the state of the load is now different. 消耗电力不同。 Different power consumption.

[0022] 因此,如文献1那样,仅根据图像形成装置的使用方法(印刷设定)来设定固定值,不能评价伴随图像形成装置的历时变化的消耗电力的变动。 [0022] Thus, as described in document 1, the use (print setting) is formed only by means of fixed value is set according to the image, the image can not be evaluated along with the change over forming apparatus consumes power variation. 假设,图像形成装置的制造者使用图像形成装置的试作机,施以时间来设计了固定值,在使用金属模具量产的实际的图像形成装置中,会需要微修正参数固定值。 Test machine manufacturers use the image is assumed, the image forming apparatus forming apparatus, designed to impose a fixed time value, means, correction parameter will need a micro fixed value in an actual image is formed using a metal mold for mass production. 因此,根据修正的规模,在图像形成装置的量产开始后,会需要参数的修正作业。 Thus, according to the modified scale, mass production after the start of the image forming apparatus, the operating parameters may require revision. 若该修正作业花费时间,则根据情况,会导致不得不延期图像形成装置的发售的事态。 If the correction operation takes time, according to the situation, it will lead to the sale of the situation had to be postponed image forming apparatus.

[0023] 文献2的技术存在下述问题,即当欲测量图像形成装置的各负载的消耗电力时,需要按各负载设置根据各负载的消耗电力的大小的累计电量计,会导致装置的复杂化。 [0023] Document 2 has a problem, i.e., when the power consumption of each load to be measured when the image forming apparatus, the load required for each electricity meter is provided according to the size of the total power consumption of each load, will result in a complex apparatus of.

[0024] 另外,以MFP为代表的图像形成装置的电力消耗具有以下的特征。 Power [0024] Further, as the representative MFP consumption image forming apparatus has the following features. 当图像形成装置的动作状态处于暖机中时,图像形成装置由于进行将定影器加热至规定的温度的动作等,因此要连续地消耗数百瓦特至千数百瓦特的程度的电力。 When the operating state of the image forming apparatus is in warm-up, since the image forming apparatus performs a predetermined operation to the heating temperature of the fixing device, therefore continuously consuming hundreds of watts to several hundred one thousand watts of power level. 当图像形成装置的动作状态为打印中时,图像形成装置进行用于打印的电机的驱动等,因此会连续地消耗数百瓦特的程度的电力。 When the operating state of the image forming apparatus is printing, the drive motor of the image forming apparatus for printing and the like, and therefore will consume hundreds of watts continuous power level. 同时,图像形成装置由于进行定影器的温度控制动作,因此断续地会消耗千数百瓦特的程度的电力。 Meanwhile, since the image forming apparatus controls the operation temperature of the fixing device, thus intermittently consumes one thousand several hundreds watts power level. 当图像形成装置的动作状态为待机中时,图像形成装置因控制电路等会连续地消耗数十瓦特的程度的电力。 When the operation of the image forming apparatus in the standby state, the control circuit means due to continuously consume a power level of several tens of watts of image formation. 同时,图像形成装置由于定影器的温度控制,会断续地消耗千数百瓦特的程度的电力。 Meanwhile, the image forming apparatus due to the temperature control of the fixing device, consumes one thousand several hundreds watts power level intermittently. 当图像形成装置的动作状态为休眠模式等省电力模式中时,图像形成装置因控制电路部等会长时间持续地消耗数瓦特的程度的小电力。 When the operation state of the image forming apparatus to the sleep mode in power saving mode, the image forming apparatus by the control circuit section and the like will be long lasting wattage consumed little power level.

[0025]用时间轴对上述的各个动作状态中的消耗电力取值时,最大消耗电力状态的时间的比率少,最小消耗电力状态(省电力模式)的时间的比率最高。 Ceiling [0025] When the power consumption value of each of the above operation state with a time axis, the ratio of the maximum power consumption low state time, the minimum power consumption state (power saving mode) time.

[0026] 因此,例如当测量1周或者1个月这样的长期间内的消耗电量时,消耗电力的变动大,消耗电力的计测设备需要能够精度良好地计测从低消耗电力到高消耗电力的宽范围的消耗电力。 [0026] Thus, for example, when the measured power consumption during such a long month, or one week, a large variation in power consumption, the power consumption of the measuring device needs to be able accurately measured from high to low power consumption consumption a wide range of power consumption of electric power.

[0027]例如,若欲利用插入初级侧的消耗电力测量电路精度良好地计测宽范围的消耗电力,则消耗电力测量电路需要具有与通用计测器相同程度的性能,从而存在图像形成装置的构成复杂且昂贵这一问题。 [0027] For example, using Ruoyu circuit consumes power measurement accuracy satisfactorily insert the primary side of a wide range of measuring the power consumption, the power consumption of the measurement circuit is required to have the same level of performance with the universal measuring device, so that there is an image forming apparatus a complex and expensive issue. 另外,当向初级侧插入了消耗电力测量电路时,需要消耗电力测量电路中的检测电路与使检测结果显示的部分之间的绝缘,从而存在图像形成装置的构成复杂且昂贵这一问题。 Further, when inserting the power consumption measurement circuit to the primary side, the detection circuit consumes power measuring circuit with a detection result of the insulation between the portions of the display, so that there is a complex and expensive issue of the image forming apparatus. 具体而言,当基于将初级侧的电流值变换为AD (模拟数字)而得到的值来计算消耗电量时,要测量的电流值的变动大,因此10比特左右的廉价的AD变换器的电流的测量精度差。 Specifically, when the value based on the current value converted to the primary side of the AD (analog-digital) obtained by calculating the power consumed by the current value of the variation to be measured is large, a current of approximately 10 bits thus inexpensive AD converter difference measurement accuracy.

[0028] 近些年,排出的二氧化碳、消耗电量的具体的削减目标要用数值来表示,对消耗电量的测量精度的要求变得更严格。 [0028] In recent years, carbon dioxide emissions, power consumption reduction target specific value to use to represent the requirements of the measurement accuracy of the power consumption amount becomes more stringent. 但是,文献3以及4技术对于伴随要测量的电力范围的宽度的消耗电量的测量精度的恶化却完全没有考虑。 However, the deterioration of the measurement accuracy Document 3 and 4 the width art power range to be measured along with power consumption but is not considered.

[0029] 当从负载变动这一观点考虑图像形成装置的消耗电力时,除上述那样的图像形成装置的动作状态所引起的变动之外,还存在纸张的种类、设置环境或者历时劣化等所引起的负载变动。 [0029] When considering the power consumption of the image forming apparatus from the load fluctuation this point, in addition to the above changes in the operation state of the image forming apparatus caused by the type of paper there is provided the environment and the like caused by aged deterioration or load variations. 例如当关注定影器时,除熔解调色剂来定影所需的能量以外,还存在被纸张占用的热量。 For example, when focusing on the fuser, in addition to the desired fixing energy to melt the toner, there is also occupied by the sheet of heat. 该热量较大地依赖于纸张的厚度、纸张的水分量,因此根据纸张的种类,定影器所需的热量变动。 The large amount of heat depends on the thickness of the sheet, the amount of moisture in the paper, thus depending on the type of paper, fuser heat required changes. 另外,驱动图像形成装置的电机的负载转矩依赖于环境。 Further the load torque of the motor driving the image forming apparatus depending on the circumstances. 例如在低温环境下,由于电机内的润滑脂的硬化等,消耗电力增加。 For example at low temperatures, due to the hardening of the grease in the motor, the power consumption increases. 进而,由于图像形成装置的各部件的历时劣化,新产品的状态的图像形成装置与长期间使用后的图像形成装置的负载转矩存在差异,消耗电力变动。 Further, differences in load torque device, the power consumption changes due to the aged deterioration, new product image state of each member of the image forming apparatus using the image forming apparatus with a long period.

[0030] 进而,电子照片处理中不可缺少的高压电源根据图像稳定化动作来调整其输出电压、输出电流。 [0030] Further, the electrophotographic process indispensable to the high voltage power supply adjusts its output voltage, output current according to the image stabilization operation. 因此,高压电源的消耗电力不是恒定的。 Thus, the power consumption of the high voltage power supply is not constant. 冷却风扇等为了实现静音化,通常不旋转,也通过监视温度等来控制其旋转。 A cooling fan in order to achieve noise reduction, typically does not rotate, the rotation is also controlled by monitoring the temperature and the like.

[0031] 这里,现有技术有下述消耗电力的计算方法,即预先准备根据动作模式和要复印的原稿的张数或者要打印的纸张的份数的消耗电力的参数,使用该参数来计算消耗电力。 [0031] Here, the calculation method of the prior art has the following power consumption, i.e., the parameters are prepared in advance in accordance with the power consumption of the number of parts and the operation mode of the document to be copied or printed sheets to be used to calculate the parameter power consumption. 该方法能够用恰当的精度计算因动作模式的不同引起的消耗电力的差。 This method can calculate the difference between the power consumption varies due to the operation mode with the appropriate accuracy. 但是,该方法在计算消耗电力的绝对值时,需要环境条件、耐久条件、图像形成条件、纸张种类、纸张厚等大量的参数(信息),若要提高消耗电量的检测精度,则需要庞大的程序。 However, this method when calculating the absolute value of the power consumption, it is necessary environmental conditions, durability conditions, a large number of image forming parameters, the type of paper, thick paper, etc. (information), to improve the detection accuracy of the power consumption amount is required huge program. 结果,需要庞大的程序的开发、用于确定参数的验证作业。 As a result, it requires a huge development program for validation work to determine the parameters.

[0032] S卩,以往未提出在提高图像形成装置的消耗电力的检测精度时,兼顾产品成本与开发成本的适当的电力测量方法。 When the [0032] S Jie, the detection accuracy of the conventional power consumption in enhancing the image forming apparatus is not made, taking into account the appropriate power measurement method of the product cost and development cost.

[0114] 在上述的消耗电量的计算方法中,通过配合图像形成装置的电力消耗的实际情况、历时的或者耐久的消耗电力的变化,区分为利用计算来计算消耗电量的部分和利用实际测量来计算消耗电量的部分,来计算消耗电量,从而实现容易设计、精度高的方法。 [0114] In the calculation of the power consumption amount of process, the actual power consumption of the device is formed by fitting an image or durable consumption over the change in power, divided into calculated using calculating section and utilizing the power consumption of the actual measurement power consumption calculation section to calculate power consumption, thereby realizing easy design, high accuracy method.

[0115] 在计算图像形成装置的消耗电量的情况下,不仅需要考虑打印动作中的消耗电量,还需要考虑也包含待机中的消耗电量、休眠模式中的消耗电量的综合的消耗电量。 The case where [0115] the power consumption in a computing apparatus for forming an image, needs to consider not only the power consumption in the printing operation, also need to consider also comprise a standby power consumption, the power consumption in the sleep mode of the integrated power consumption. 从该观点来看,优选用被称为TEC (Typical Electricity Consumpt1n)值的消耗电量来进行讨论。 From this viewpoint, preferably used are referred to as TEC (Typical Electricity Consumpt1n) power consumption value for discussion. TEC值是以规定的量进行了打印动作后,经由规定的停止再次进行规定的打印动作时的消耗电量,并以也假设了设想夜间、休息日的休眠模式的时间的形式测量消耗电量。 After the prescribed amount of the TEC is carried out printing operation, via predetermined stop power consumption when printing performs a predetermined action again, and to also assume that the idea of ​​the night as a time of rest days sleep mode power consumption measurements.

[0116] 若分析构成TEC值的消耗电量,则为如下这样的详细内容。 [0116] If the analysis of the power consumption of the TEC configuration, as compared with such details.

[0117] 休眠模式下的消耗电量....29% [0117] Power consumption in sleep mode .... 29%

[0119] 打印中的消耗电量(控制部除去定影加热器)....3% [0119] printing power consumption amount (fixing heater control unit removed) .... 3%

[0120] 打印中的消耗电量(定影加热器)....55% [0120] The power consumption printing (fixing heater) .... 55%

[0121] 打印任务结束后,若不执行下一打印,则在规定的时机移向休眠模式(省电力模式)。 The timing of the end of [0121] the print job without performing the next print, then moved to the prescribed sleep mode (power saving mode). 另外,由于夜间、休息日也不执行打印,因此为移向长时间休眠模式的状态。 In addition, because at night, rest day nor printing is performed, so long as the move to a sleep mode state. 在这些休眠模式下消耗的累计的消耗电量占TEC值的29%。 The cumulative consumption of power consumption in sleep mode which accounted for 29% TEC values. 该情况下,驱动负载部、定影加热器不进行动作,因此图像形成装置整体的消耗电量为仅控制部的消耗电量。 In this case, the drive load unit, the fixing heater does not operate, so the overall power consumption of the image forming apparatus consumes power only to the control unit. 另一方面,当从休眠状态接受了打印指示时,图像形成装置进行暖机动作,在暖机完成的同时进行打印动作,若打印动作结束,则返回休眠模式。 On the other hand, when receiving a print instruction from the sleep state, the image forming apparatus warming operation, the printing operation is completed at the same time the warm-up, if the printing operation is completed, the sleep mode is returned. 占该一系列的动作的消耗电量的累计值的驱动负载部、控制部以及定影加热器的消耗电量分别为13%、3%以及55%。 Grand total value of the power consumption of the series of operations of the drive load unit, a control unit and a fixing heater consumption amount were 13%, 55% and 3%.

[0122] 在休眠模式的情况下,图像形成装置仅残留用于接受打印指示的最小限的功能,此外的控制停止。 [0122] In the case of the sleep mode, only the image forming function for the minimum remaining print instruction receiving means, in addition to the control stop. 因此,消耗电力的变动少。 Therefore, the change in power consumption of less. 因此,在为休眠状态时,能够根据其动作时间精度良好地求出消耗电量。 Accordingly, when the sleep state, power consumption can be obtained favorably according to its operation time accuracy.

[0123] 打印中的控制部的消耗电量基于“根据打印模式不同的图像处理的状态”和“打印模式的动作时间”来计算。 [0123] The printing control unit based on the power consumption amount "state in accordance with a print mode different image processing" and "print mode operation time" is calculated.

[0124] 打印中的驱动负载部的消耗电量因环境、装置的耐久等容易产生变动。 [0124] Power consumption in driving load of the printing unit due to environmental, durability and other devices prone to fluctuation. 因此,驱动负载部的电源系统(多数情况下为24V)的消耗电量基于实际测量出的电流来计算。 Thus, the power supply system for driving a load unit power consumption (in most cases to 24V) is calculated based on the actually measured current. 优选电流的测量以与控制部控制电机的动作的周期(主程序的周期)同步的周期进行。 Measurement is preferably carried out in the current cycle of operation of the motor and the control unit controls (main routine) of the synchronization period. 驱动负载部通过控制部来判断按规定周期要被开启还是被关闭,根据判断结果来进行开启或者关闭。 Load drive unit by the control unit determines predetermined period is to be turned off or to be turned on or off according to the determination result. 因此,电流的变化成为与该周期对应的动作。 Thus, the change in current becomes a period corresponding to the operation.

[0125] 打印中的定影加热器的消耗电量基于“定影加热器的额定消耗电力”和“定影加热器的动作时间”来计算。 [0125] The fixing heater consumption amount of printing is calculated based on the "rated power consumption of the fixing heater" and "a fixing heater operation time." 定影加热器的额定消耗电力与实际的加热器的消耗电力的差作为加热器的部件公差被管理,因此可以进行精度管理。 It is managed as a difference component tolerances heater fixing heater rated power consumption and the actual power consumption of the heater, thus precision control can be performed.

[0126] 这里,为了防止在开启或者关闭定影加热器的过渡时流过浪涌电流,或者为了防止起因于开启或者关闭的初级侧的电压变动,有时在进行点亮或者熄灭的情况下,要渐渐地使消耗电力变化。 [0126] Here, in order to prevent opening or closing the flow when the transition of the fixing heater inrush current, or to prevent the voltage fluctuation due to the primary side is turned on or off, and sometimes during the turn on or off the case, to gradually the power consumption change. 该情况下,通过对定影加热器的消耗电量的计算加入修正的计算,可以进行正确的消耗电量的计算。 In this case, by calculating the power consumption of the fixing heater was added correction calculation can be correctly calculated power consumption amount. 优选定影加热器的动作时间与进行定影加热器的开启关闭控制的控制周期同步地被测量。 Preferably the fixing heater operation time and turn off a fixing heater control cycle is measured in synchronization with the control.

[0127] 如上述那样,基于实际测量的电流值来计算驱动负载部的消耗电量,基于动作状态预测来预测此外的部分的消耗电量,从而可以精度良好地求出消耗电量。 [0127] As described above, the current value is calculated based on actual measured power consumption of the drive portion of the load operation state of the prediction based on the predicted power consumption amount addition section, can be accurately determined power consumption.

[0128]图6是表示本发明的一实施方式的消耗电量的计算所涉及的图像形成装置的动作的流程图。 [0128] FIG 6 is a flowchart illustrating an image apparatus calculates the power consumption amount to an embodiment of the present invention is formed. 图6所示的流程图例如通过控制部103的CPU331下载保存于控制部103的R0M333的控制程序来执行。 The flowchart shown in FIG. 6, for example, to download stored by the control unit 103 CPU331 R0M333 control program in the control unit 103 to perform.

[0129] 参照图6,控制部103开始计时器执行的计时(S1),进行输入处理(S2)。 [0129] Referring to Figure 6, controls the timing (S1) the timer unit 103 starts execution, input processing (S2). 然后,控制部103判别选择怎样的模式作为图像形成装置的动作状态(S3)。 Then, the control unit 103 determines the image of the selected mode as the operating state (S3) forming means.

[0130] 在步骤S3中,当选择了省电力模式(休眠模式)时,控制部103进行省电力控制 [0130] In step S3, when selecting the power saving mode (sleep mode), the control unit 103 performs power saving control

(S9),进入步骤S13的处理。 (S9), the process proceeds to step S13. 进而,在步骤S3中,当选择了打印模式时,控制部103进行打印控制(S11),进入步骤S13的处理。 Further, in step S3, when the printing mode is selected, the control unit 103 performs printing control (S11), the process proceeds to step S13.

[0131] 在步骤S13中,控制部103进行输出处理(S13),进行AD (模拟数字)变换处理(S15)。 [0131] In step S13, the control unit 103 performs output processing (S13), for AD (analog-digital) conversion processing (S15). 然后,控制部103进行通过第1电力计算部103e计算驱动负载部105以及后处理装置210的消耗电量的处理(S17),进行通过第2电力计算部103f计算定影加热器83的消耗电量的处理(S19)。 Then, the control unit 103 performs processing (S17) calculating power consumption for driving a load unit 105 and post-processing device 210 by the first power calculating unit 103e, processing of calculating power consumption amount of the fixing heater 83 by the second power calculation unit 103f (S19). 然后,控制部103进行通过第3电力计算部103g计算操作显示控制部103a、图像控制部103b、驱动负载控制部103c以及定影加热器控制部103d的合计的消耗电量的处理(S21),进行由第4电力计算部103h执行的计算后处理装置220的消耗电量的处理(S23)。 Then, the control unit 103 performs control unit 103a, image control section 103b, the total power consumption of the load drive control section 103c, and 103d of the fixing heater control unit process (S21) displayed by the third calculating portion 103g calculates the power operation, by calculating a fourth power calculator 103h performs post-processing of the consumption amount of process 220 (S23) device. 当图像形成装置不包含后处理装置220时,步骤S23的处理被省略。 When the image forming apparatus 220 does not comprise processing means, the processing of step S23 is omitted. 其次,控制部103通过电力合计部103i进行由第1〜第4电力计算部103e〜103h(或者第1〜第3电力计算部103e〜103g)计算出的消耗电量的合计处理(S25)。 Next, the control unit 103 performs processing for calculating the sum by the 103e~103h (1 ~ 3 or the second power calculator 103e~103g) of the fourth power calculator 1 ~ consumption amount (S25) by the sum of the power section 103i. 然后,控制部103在显示部102进行电力信息的显示处理(S26),在显示部102显示消耗电量的模式、即电力显示模式通过操作部101来判别是否被设定(S27)。 Then, the control unit 103 on the display unit 102 displays information processed power (S26), the power consumption of the display mode on the display unit 102, i.e., determines whether the electric power display mode is set (S27) through the operation section 101.

[0132] 在步骤S27中,当判别为设定了电力显示模式时(在S27中,是),控制部103在显示部102显示消耗电量(S29),进入步骤S33的处理。 [0132] In step S27, when the determined power display mode is set (in S27, the Yes), the control unit 103 displays the power consumption (S29), the processing proceeds to step S33 on the display unit 102. 另一方面,在步骤S27中,当判别为未设定电力显示模式时(在S27中,否),控制部103从显示部102消去消耗电量的显示(S31),进入步骤S33的处理。 On the other hand, in step S27, when it is determined when the power display mode is not set (in S27, the No), the control unit 103 displays erasing (S31) from the consumption amount of the display unit 102, into the process of step S33.

[0134][第1电力计算部的消耗电量的计算方法] [0134] [Calculation method of the first electric power consumption amount calculating portion]

[0135] 然后,对第1电力计算部103e的消耗电量的计算方法进行说明。 [0135] Then, the first method of calculating a power consumption amount calculation unit 103e will be described.

[0136] 图7是用于说明第1电力计算部103e所执行的驱动负载部105以及后处理装置210的消耗电量的计算方法的电路图。 [0136] FIG. 7 is a circuit diagram for explaining a method of calculating a first portion of a load driving power calculator 103e executed by the power consumption of the post-processing apparatus 105 and 210.

[0137] 参照图7,电源部106包含低压电源106a。 [0137] Referring to FIG 7, power supply unit 106 comprises a low voltage power supply 106a. 低压电源106a与多个负载LD相互并联连接。 A plurality of low voltage power supply 106a and the load LD are connected in parallel to each other. 低压电源106a是额定输出电源,将初级侧(电源部106前的商用电源侧)的电压变换为次级侧(电源部106后的负载LD侧)的额定电压(例如24V),以变换后的电压向各负载LD供给电力。 Low voltage power supply 106a is the nominal output power, the primary side (the front side of the commercial power supply portion 106) of the voltage into the secondary side (load LD rear side of the power supply portion 106) of the rated voltage (e.g. 24V), transformed to the voltage power supply to each load LD. 负载LD是与驱动负载部105的各驱动部或者后处理装置210对应的部件。 210 corresponding to the load LD is a member driving unit for driving the respective load unit 105 or post-processing apparatus. 低压电源106a与各负载LD之间的电力供给路径与电流检测电阻301连接。 Low voltage power supply 106a connected to the power supply path and the current detection resistor 301 between the load LD. 电流检测电阻301中流过使流过所有的负载LD的电流合流后的电流。 Current detection resistor 301 current flows through the current merging all the load LD flows.

[0138] 第1电力计算部103e按时间T1 (s)对例如将流过电流检测电阻301的电流进行AD变换后的值、即电流Ml (A) (24V电流监视器的AD变换值)进行次数N1的计测(采样)。 [0138] The first power calculator 103e time T1 (s), for example, a current detecting resistor 301 of the current flowing through a value after AD conversion, i.e. a current Ml (A) (AD converted value of the current monitor 24V) of N1 is the number of measurement (sampling). 时间T1是采样周期,次数N1是采样点数。 T1 is the sampling period of time, N1 is the number of sampling points. 时间T1以及次数N1分别按照时间T1与次数N1的积为1 (s)的方式设定,例如被保存于R0M333。 T1 and N1 are frequency and time according to the time T1 and the product of the number N1 is 1 (s) is set in, for example, is stored in R0M333. 在本实施方式中,如图8所示,时间T1被设定为5 (ms),次数N1被设定为200 (次)。 In the present embodiment, as shown in FIG. 8, the time T1 is set to 5 (ms), the number of times N1 is set to 200 (times).

[0139] 第1电力计算部103e基于计测到的电流Ml和次级侧的额定电压,来计算每l(s)的次级侧的消耗电量(Ws)。 [0139] The first power calculator 103e based on the rated current to the voltage measuring Ml and a secondary side, the power consumption amount calculated per l (s) of the secondary side (Ws). 各负载LD的开启关闭状态在打印序列中复杂地变化,因此通过实际测量流过电流检测电阻301的电流,基于实际测量到的电流来计算次级侧的消耗电量,可使消耗电量的精度提高。 Each load LD is turned off in a state changes complicatedly printing sequence, so by measuring the actual current flowing through the current detection resistor 301, a current actually measured power consumption amount is calculated based on the secondary side of the power consumption amount can improve the accuracy of . 另外,优选第1电力计算部103e将次级侧的消耗电量换算为初级侧的消耗电量(Ws)。 Further, preferably the first calculating unit 103e to the power consumption amount of the secondary side is converted into the primary side of the power consumption amount (Ws). 低压电源106a用于根据电流(次级侧的电流)的大小来变动变换效率。 It means for low voltage power supply 106a changes according to the magnitude of the current conversion efficiency (secondary current) is. 当将次级侧的消耗电量变换为初级侧的消耗电量时,优选使用例如图9所示那样的变换效率表。 When the secondary-side power consumption amount is converted into the primary side of the power consumption amount, for example, it is preferably used as the conversion efficiency shown in Table 9 in FIG. 之后,第1电力计算部103e向电力合计部103i通知计算信息。 Thereafter, the first power calculating unit 103e calculates the total power information notification portion 103i.

[0140] 图10是表示第1电力计算部103e执行的消耗电量的计算处理的流程图。 [0140] FIG. 10 is a flowchart of a process calculated consumption amount calculation unit 103e first power performed. 图10所示的流程图作为图6的步骤S17中的处理的子程序被执行。 Flowchart shown in FIG. 10 subroutine processing S17 is performed as in step 6 of FIG.

[0141] 参照图10,第1电力计算部103e计测流过电流检测电阻301的电流Ml (S101),并在累计电流El上加上电流M1(S103)。 [0141] Referring to FIG 10, the first 1 103e power calculator measuring the current flowing through the current detecting resistor 301 Ml (S101), and an electric current of M1 (S103) to the accumulated current El. 然后,第1电力计算部103e计算变量η是否达到了200 (是否经过了1 (s)的时间)(S105)。 Then, the first calculating unit 103e calculates the power has reached the variable η 200 (whether a 1 (S) time) (S105).

[0142] 在步骤S105中,当判别为变量η达到了200时(在S105中,是),第1电力计算部103e通过用200去除累计电流E1,来计算电流Ml的1 (s)间的平均值E (S107)。 [0142] In step S105, when determined that the variable η reaches the 200 (in S105, YES), first power calculating unit 103e by 200 removes accumulated current E1 used to calculate the current Ml of 1 (S) between the average value of E (S107). 然后,第1电力计算部103e基于平均值E与额定电压(24V),来计算每1 (s)的次级侧的消耗电量N(S109)。 Then, the first calculating unit 103e based on the average power E rated voltage (24V), calculated per 1 (S) of the secondary side of the power consumption amount N (S109). 然后,第1电力计算部103e将次级侧的消耗电量N变换为每1 (s)的初级侧的消耗电量A (Sill)。 A primary side of the power consumption amount and then, the first calculating unit 103e to the power consumption amount of the secondary-side converting N per 1 (S) a (Sill). 在步骤Sill中,使用例如图9所示的变换效率表,求出电流为平均值E时的变换效率,通过用求出的变换效率去除次级侧的消耗电量N,来计算初级侧的消耗电量A。 In step Sill, the conversion efficiency of the example table shown in FIG. 9, the conversion efficiency is obtained when the current average value of E, by removing the power consumption of the secondary-side N obtained by the conversion efficiency, calculated consumption of the primary side power A. 然后,第1电力计算部103e向电力合计部103i通知初级侧的消耗电量A (S113),将变量η以及累计电流El的值清零(S115),并返回。 Then, a first portion of the total power calculator 103e notifies 103i consumption amount A (S113) to the primary side of the power, and the variable η El integrated current value is cleared (S115), and returns.

[0143] 在步骤S105中,当判别为变量η未达到200时(在S105中,否),第1电力计算部103e使变量η自加1 (S117),并返回。 [0143] In step S105, if determined that the variable η 200 not reached (in S105, the No), the first power calculating unit 103e from adding the variable η 1 (S117), and returns.

[0144][第2电力计算部的消耗电量的计算方法] [0144] [2 Calculation of power consumption amount calculating portion]

[0145] 然后,对定影装置8为卤素定影器时的(定影加热器83为卤素加热器的情况)第2电力计算部103f的消耗电量的计算方法进行说明。 (Fixing heater 83 is a halogen heater case) calculated second power consumption amount calculation unit 103f will be described when the [0145] Then, the fixing means fixing device 8 is halogen.

[0146] 当定影装置8是使用了卤素加热器(卤素灯)的定影器、即卤素定影器时,在将流过定影加热器83的电流抑制在额定电流(例如15A或者20A)以下的状态下,暖机时间需要满足规定的条件(产品规格)。 [0146] When the fixing device 8 using a halogen heater (halogen lamp) fixing device, i.e. a halogen fixing device, the current flowing through the fixing heater 83 is suppressed state in the rated current (e.g., 15A or 20A) or less , the warm-up time required to meet specified conditions (specifications). 因此,定影加热器83 (复印机用的卤素加热器)中的针对额定电力的实际的消耗电力或者定影加热器83产生的热量严格地被管理。 Therefore, the heat of the fixing heater 83 (halogen heater copying machine) the actual power consumption or for the fixing heater 83 generates rated power is strictly managed. 因此,定影加热器83为开启的状态下的消耗电力的变动小。 Thus, the fixing heater 83 to change the power consumption in a small opening state. 若着眼于该事实,则作为卤素定影器的定影加热器83的消耗电量能够基于定影加热器83的额定电力和向定影加热器83的通电时间来正确地计算。 When focusing on this fact, it can be accurately calculated based on the rated power and the fixing heater energization time of 83 to the fixing heater 83 as the fixing heater 83 is a halogen fuser power consumption.

[0147] 图11是用于说明定影装置8为卤素定影器时的第2电力计算部103f所执行的定影加热器83的消耗电量的计算方法的概念图。 [0147] FIG. 11 is a fixing device 8 is a conceptual diagram of the method of calculating power consumption of the fixing heater 83 to the second power calculator 103f halogen fixing device when executed.

[0148] 参照图11,当对定影装置8进行通常的控制时,如(a)所示,第2电力计算部103f将定影加热器83的额定电力作为向定影加热器83的接通电力,通过定影加热器83的额定电力与通电时间的积来计算定影加热器83的消耗电量。 [0148] Referring to FIG 11, when the fixing device 8 performs normal control, such as (a), the second power calculation portion 103f of the fixing heater 83 as the rated power is turned on power to the fixing heater 83, calculating power consumption of the fixing heater 83 by the product of the rated power energization time of the fixing heater 83. 另一方面,当定影加热器开启时或者关闭时,以防止浪涌电流引起的定影加热器83的损伤为目的,有时进行使流过定影加热器83的电流缓慢地增加的控制(上升(Through up)控制)或者使流过定影加热器83的电流缓慢地减少的控制(下降(Through down )控制)。 On the other hand, when the fixing heater is turned on or off, to prevent damage to the fixing heater 83 due to the inrush current for the purpose, may be a current flowing through the fixing heater 83 is controlled gradually increased (increased (Through up) control) or the current flowing through the fixing heater 83 is controlled gradually reduced (down (through down) control). 在进行这些控制时,如(b )所示,第2电力计算部103f基于刚开始定影加热器83的动作后以及动作刚停止前的过渡状态下的定影加热器83的消耗电力的变化来修正消耗电量。 During these controls, such as (b), the second power calculation unit 103f based on a change in the power consumption of the fixing heater 83 immediately after the start of operation of the fixing heater 83 in a state before transition and immediately stop the operation to fix power consumption. 具体而言,第2电力计算部103f通过从定影加热器83的额定电力与通电时间的积减去上升控制时的修正消耗电量AM1以及下降控制时的修正消耗电量AM2,来计算定影加热器83的消耗电量。 Specifically, the second power calculation unit 103f AM2, the fixing heater 83 is calculated by subtracting the correction AM1 power consumption is increased when the power consumption amount and a correction control when the power-down control from the product of the nominal energization time of the fixing heater 83 the consumption of electricity.

[0149] 此外,第2电力计算部103f也可以仅基于动作刚开始后以及动作刚停止前中的任意一个过渡状态来修正消耗电力。 [0149] Further, the second power calculation unit 103f may be based on only the operation after the operation started and stopped just before the transient state in any of a corrected power consumption.

[0150] 然后,说明定影加热器83由长加热器以及短加热器2个卤素加热器构成时的定影加热器83的消耗电量的计算方法的一个例子。 [0150] Next, the example of a method of calculating power consumption of the fixing heater 83 when the fixing heater 83 is constituted by long heater and the short heater 2 halogen heater. 长加热器以及短加热器各自的额定电力如图12所示,为1180 (W)以及790 (W)。 Long heater and the short heater at their nominal power 12, is 1180 (W), and 790 (W).

[0151] 图13是表示定影装置8的典型的点亮模式的图。 [0151] FIG. 13 is a diagram showing a typical mode of fixing the lighting device 8.

[0152] 参照图13,当定影加热器83在时刻tl开启时,通过上升控制,定影加热器83的消耗电力与时间成正比例增加至额定电力。 [0152] Referring to FIG 13, when the fixing heater 83 is turned on at time tl, through the rise control, the power consumption is proportional to the time of the fixing heater 83 is increased to the rated power. 若定影加热器83的消耗电力在时刻t2增加至额定电力,则定影加热器83为全点亮的状态,消耗电力为恒定。 If the power consumption of the fixing heater 83 is increased to the rated power at time t2, the whole state of the fixing heater 83 is turned on, the power consumption is constant. 当定影加热器83在时刻t3关闭时,通过下降控制,定影加热器83的消耗电力与时间成正比例减少至关闭时消耗电力。 When the fixing heater 83 off at time t3, by the lowering control, the fixing heater power consumption is proportional to the time to reduce power consumption during off 83. 关闭时消耗电力对于长加热器为500 (W),对于短加热器为335 (W)。 When the power consumption is close to the length of the heater 500 (W), for a short heater is 335 (W). 若定影加热器83的消耗电力在时刻t4减少至关闭时消耗电力,则定影加热器83全熄灭。 If the power consumption of the power consumption of the fixing heater 83 is reduced to turn off at time t4, then the whole of the fixing heater 83 is off.

[0153] 当定影装置8为卤素定影器时,第2电力计算部103f计测定影加热器83为某相位控制状态时的经过时间,并且按时间T2对定影加热器83的相位控制状态进行次数N2的采样。 [0153] When the fixing device 8 is halogen fixing device, the second power calculator 103f Movies heater 83 is measured when the elapsed time of a phase control state, and the state of the phase control of the fixing heater 83 is performed by Time T2 N2 sampling. 时间T2是采样周期,次数N2是采样点数。 T2 is the sampling time period, N2 is the number of sampling points. 时间T2以及次数N2分别按照时间T2与次数N2的积为1 (s)的方式被设定,并例如被保存于R0M333。 T2, and N2 are the number of times according to the time T2 and the product of the number N2 of embodiment 1 (s) is set to, for example, and is stored in the R0M333. 在本实施方式中,时间T2被设定为5 (ms),次数N2被设定为200 (次)。 In the present embodiment, the time T2 is set to 5 (ms), the number N2 is set to 200 (times). 定影加热器83的相位控制状态是指例如定影加热器83的全点亮状态、全熄灭状态、上升控制状态或者下降控制状态等。 Phase control state of the fixing heater 83 is, for example a fixing heater 83 in a full lighting state, a full off state, the control state rising or falling control status. 而且,第2电力计算部103f在相位控制状态被切换时,基于切换前的相位控制状态的种类与切换前的相位控制状态的经过时间,来计算每1 (s)的定影加热器83的消耗电量(Ws)。 Further, the second power calculator 103f when the phase control state is switched, the control state based on the elapsed time phase before the phase control type switching state before switching, calculated per 1 (s) 83 of the fixing heater consumption power (Ws). 之后,第2电力计算部103f向电力合计部103i通知计算信息,再计测变更后的相位控制状态的经过时间。 Thereafter, the second power calculation unit 103f calculates the total power information notification unit 103i, and then count the phase control state changes measured elapsed time.
